This fall, TV networks boast their most addictive shows yet—from Glee's Britney-loving sophomore season to Conan's cable debut, you'll know where to find us. On the sofa. Here are 10 reasons why.

When the ABC laugh riot Modern Family debuted last fall, creators Steven Levitan and Christopher Lloyd revived the family sitcom by making often pallid material—raising children, maintaining a marriage—new again. (Effeminately gay dad Cameron might just be the most hilarious homemaker archetype we've seen since Carol Brady.) This season, FOX's Raising Hope continues to push the genre forward with politically incorrect jokes and its expertly cast uncouth brood: Martha Plimpton is at her best as a chain-smoking, foul-mouthed mom, and Cloris Leachman amuses (and horrifies) as a semisenile grandma who can't keep her bra on.

FOX phenom Glee returns for season two, giving lovable but lobotomized ditz Brittany (Heather Morris) her moment at the mic in a—what else?—Britney Spears–themed episode. Creator Ryan Murphy, who developed the Britney-Brittany story line after Gleeks launched a Twitter campaign championing the idea, has already dubbed it hallucinogenic. If that's not enough to make you want to go Gleek, John Stamos makes his debut this fall as Emma's dentist/love interest (Justin Timberlake, as rumored, will not), and the cast will pay tribute to the campiest musical comedy of them all, The Rocky Horror Picture Show.
